Multiple variable speed touch pad cursor control method

Abstract

The invention relates to a multiple variable speed touch pad cursor control method which is used in a system that a touch pad controls a screen cursor and used for converting a translocation vector of fingers into a translocation vector of the screen cursor. The screen cursor is distinguished by using at least one starting state and one closing state according to the state of the touch pad in accordance with the finger touch; and a value obtained by multiplying speed parameters calculated by at least more than two different conversion formulas by finger coordinate change vectors is used as a moving vector of the screen cursor according to different changes of the pressing time and the finger displacement; therefore, the invention provides a control function that different cursor moving speeds and mouse key functions are switched according to the demands of a user so as to increase the convenience for the user to the cursor control.

Description

technical field [0001] The present invention relates to a mouse board cursor control method with multiple variable speeds, thereby providing users with the ability to switch between different cursor moving speeds according to requirements, thereby increasing the convenience of cursor control. Background technique [0002] There are various cursor control devices, but the mouse is the most common and easy-to-use device for general users. However, due to the limited volume, it cannot be directly installed on a notebook computer. Therefore, most notebook computers use a mouse pad as the mouse control, but it is also limited by the mouse pad. When moving the cursor on the screen for a long distance, for example, moving the cursor from the leftmost to the rightmost of the screen, the finger needs to move repeatedly on the mouse pad several times to complete it. If the finger moving speed is the same as the screen cursor If the ratio of speed is increased, the cursor can be contro...

[0002] There are various cursor control devices, but the mouse is the most common and easy-to-use device for general users. However, due to the limited volume, it cannot be directly installed on a notebook computer. Therefore, most notebook computers use a mouse pad as the mouse control, but it is also limited by the mouse pad. When moving the cursor on the screen for a long distance, for example, moving the cursor from the leftmost to the rightmost of the screen, the finger needs to move repeatedly on the mouse pad several times to complete it. If the finger moving speed is the same as the screen cursor If the ratio of speed is increased, the cursor can be controlled to move a long distance by moving the finger a small distance, and the cursor can be moved to the position by one swipe, but the cursor will move a lot when the finger shakes slightly, and it is difficult to align the fine points. target option(icon)

[0003] In order to solve this problem, the mouse board will design a dynamic speed change mechanism. When the finger moves slowly, the system will move the cursor with a smaller movement ra
